This patch series will attempt to discard the shmem and phys gem object backends from the driver, and handle the dependent objects from TTM instead. The end goal of this and other patches to come is to delete all existing backends and bring their functionality into the current i915 TTM API callbacks. The first patch in the series was actually authored by Bob Beckett, who is working on removing the internal and stolen GEM backends. However his change was essential for this series, so I've included it with the purpose of making the CI system happy. An RFC for the current patch was discussed in https://lists.freedesktop.org/archives/intel-gfx/2022-May/298082.html.
